There is not any professional program on internet like this and you can get it without any effort. I think this could be a handicap because it's dificult to believe, but it's true; try it and you'll be surprised.
It's not only a program to calculate a delaunay triangulation but you can input break-lines to get a real representation of the terrain.
The first version of this program came onto the market in 1992 and there are more of 3000 professionals working with it, civil engineers, architects, foreman builders, surveyors, mathematics, etc.
I tried the program with 1000000 of points and It had not problems to calculate it. 15 seconds. The program is more slow when you have too many break-lines, (more of 20000).
You can open until five instances of the program and work with a different DTM in each one. Only, write "LanDTM" on the command line and you'll see other 'LanDTM' window.
You can calculate the volume between two DTMs. There are two ways to get it.
The first, and more easy, is to make a "grid" for each DTM and to calculate the volume for the sum of each paraleliped formed. This is done with a single order, "Tools/Make 3D grid", where you can select between to calculate a single grid of points or a grid of points which elevation is the difference between two DTMs. After you can use "Tools/Grid Volume" to get the volume in cubic meters. The second, and more accurate, is to calculate the volume between two triangulations projecting each one of it in the other and calculating a new triangulation as result. It's a litle more complicated to explain but the calculated volume is the exact. This option is in the "Applications/DTMs intersection" in the main menu of the "graphic dialog box". After to make the DTMs intersection you can use "Applications/Model volume" in the main menu to get, in cubic meters, the total volume between them.
